.To all whom it may concern..-

Be it known that I, SAMUEL llIARTIN, of Mill Rock, in the county ofOolumbiana and State of Ohio, have invented certain new and usefulImprovements in Tricycles, of which the following is a full, clear, andexact description.

The object of my invention is to provide a new and improvedtricycle,which can be propelled by one, two, or more persons, and isespecially adapted to attain a great rate of speed and to carrypassengers or freight.

The invention consists of two drivingwheels actuated by hand and footlevers and suitable ratchet-wheel connections, of a shaft on which ismounted the driving-gear, a swinging frame and seat, of a guide-wheelmounted in turning bearings held in place by suitable connections fromthe main axle, of a device for operating the guide-wheel, and of a brakeof special construction.

The invention also consists of various parts and details, hereinaftermore fully set forth and claimed. I t

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan View, partly in section, of my improvement. Fig. 2 isa longitudinal vertical section on the lines 00 w of Fig. 1. Fig. 3 is avertical cross-section on the lines y y of Fig. 1. Figs. 4 and 5 aredetail views of the drivingwheel hub and ratchet-block. Figs. 6 and 7are detail views of the ratchetwheel. Figs. 8, 9, and 10 are detailviews of the lever and wheel carrying the sliding ratchet-wheel pawls.Fig. 11 is a sectional plan view of the guide-wheel fastening. Fig. 12is a longitudinal vertical section of the machine, the guiding-wheel andconnections being detached and parts broken away. Fig. 13 is a frontelevation showing the frame and brake system.

The main shaft A is provided near each end with the hubs B B, turningloosely on the shaft A, and on which hubs B B are mounted thedriving-wheels O O. The hubs B B are provided with recesses B on theirouter faces, in which recesses B are formed the ratchetteeth B. Theshaft A projects into each recess B with its square ends A A, on whichare secured the ratchet-blocks D, having each a recess, D, in whichslide the pawls D", and held in contact with the ratchetteeth 13 by theforce of the coiled springs D placed in the recess D between the axleend A and the pawls D A cover, D, is placed over the outer open face ofthe hub B, and secured by the nut D screwing on a bolt formed on theextreme end of the shaft A. This. cover D protects the ratchet-block Dfrom dust and mud. Next to the inner edge of the hub B is placed on theshaft A the sleeve E, provided on its rim with a screwthread, on whichis screwed the frame-block E. to which is attached the main frame F. Theframe F consists, principally, of the horizontal arms F, attached to theframeblocks E of the horizontal connecting-rod F, from which projectdownwardly the stays F on the lower end of which is hung the front endof the swinging platform G.

To the rear end of the frame-block E are secured the forked stays F*, towhich are attached the upright rods F to the lower end of which is hungthe rear end of the swinging platform G, and which rods F are connectedby the horizontal connecting-rod F- To each of the arms F is attached anupright rod, F which is onits lower end connected by the rod F with thearm F, and on its upper end by the stay F to the upright F and by theinclined stay F to the connecting-rod F. The lower ends of the uprightrods F F are connected to each other by the horizontal rod F, and thelowerends of the vertical rods F F are connected to each other by thehorizontal rod F.

To the cross-rods F", F, and F are pivoted the bent rods G, to which arepivotally connected the arms G attached to the under side of theswinging platform G.

Next to the sleeve E on the shaft A is placed the wheel 'H, carrying thefour or more pawls, H, sliding in sleeves H, formed on the wheel H, andheld in contact with the ratchet-teeth 1, formed on the outer face ofthe ratchet-wheel I, by the force of the coiled springs H The wheel H isprovided with a hub,H, in contact with the inner edge of the sleeve E,and around which hub H is placed A in any suitable manner, and isprovided on each face with the rat chet-teeth I.

On the hub l of the iat'cliet-wlteel I is placed the belt-pulley J,which turns on the same, and-is prevented from slipping off the said hubI" by the nut 1 screwed on the inner end of the hub I". The belt-pulleyJ is provided. with sleeves J, in which slidethe pawls J", held againstthe ratchet-teeth,l formed on the inner side of the ratchet wheel I, bythe force of the coiled spring J It will be seen that the ratchet-teeth1, formed on each face of the ratchet-wheel I, are engaged on the outeredge by the sliding pawls .H of the wheel H, and on the inner edge bythe sliding pawls J of the belt-pulley J.

To the connecting rod F are pivoted the lower ends of the levers K,which extend in an inclined position upward,and are provided with thehandles K. To each of these levers K is attached the end of a belt, K*,which passes downward and overa pulley, K placed on the cross rod F-,andupward over the beltpulley J, to the rim of which the other end of thebelt K is attached.

To the belt K is buckled a short strip, K, of leather or other material,to which strip K is attached the stirrup K having a foot-piece, K, andsliding on the inclined rods G, attached to the platform G. It will beunderstood that by raising the levers K, in the direc tion of the arrowa, and at the same time pressing the stirrups K which slide on the rodsGr downward, it will cause the pulley J to turn on the huh I of theratchet-wheel I by means of the belt K". The coiled spring K attached tothe rod F", will assist the lever K to resume its former position on thereturnstroke of the same in the direction of the arrow a.

To the belt-pulley J is attached one end of a coiled spring, J, theother end of the same beingsecurcd to a forked brace, J which has itslower bearing on the cross-rod F, and its upper forked end being placedover the shaft A. This coiled spring J assists the lever K to assume itsformer position on the returnstroke in the direct-ion of the arrow a.Rods G, similar to rods G", cxtendfrom the rear of the platform Gupward, and they and the rods G carry the seat G which is thus suspendedcentrally in the middle above theaxlc A, and conveniently large toadtnit two or more persons. The guide-wheel L is m unted in segmentalpieccs L, which are provided on their outer rims with grooves L, inwhich fit the blot-ks M. bolted to the castings M, which are held inposition by the inclined stay-rods M secured to the main frame F at thehorizontal cross-rod F, and additionally braced by the rods M, extendingfrom the forked rods F to the cross-rod F, and from thence to thecastings M;

To the shaft L of the guide-wheel L are attached the outer ends oftheforks N of the lever N, which imparts a turning motion to theguide-wheel L by the device now to be described.

To the horizontal cross-rod F is secured the curved rack 0, providedwith the teeth 0, in which engages the pointed pawl O, placed on thelever-frat'ne P, and held in contact with theteeth 0 by the force of thespring 0 The lever-frame P is provided with the handle I and the twosmall rollers 1? P", pivoted to the frame P, one at each side of thepawl O", and resting against the edge of the rack 0, so that when thehandle I? is moved to either side it will cause the pawl O to disengagethe rack O, and at the same time will swing the lever N sidewise. andconsequently turn the guide-wheel L. The lever N may be locked in suchside position by allowing the pawl O to again engage the respectiveteeth 0 on therack O. the handle I? and the frame P projecting radiallyfront the guide-wheel L.

-To the outer ends of the horizontal rods F are attached the brakes Q Q,one for each driving-wheel 0. Each of the brakes Q consists,principally,of the brake-frame Q, to the upper end of which is attachedthe forked brake-shoe Q The brake frame Q is provided with a slot, Q,through which passes the cross-rod F so that when the brake-frame Q ispressed downward the brake-shoe Q is forced against the rim of thedrivingwvheel C. The lower end of the brake-frame Qissecurcd to alever,U, pivotally attached to the lower cross-rod, F. This lever U is alsoprovided with brake-shoes U, and is held in its normal" position, asshown in Figs. 12 and 13. by a spring, U", attached to the lever U andthe cross-rod F; The. levers U are connected with each other by the armsU and the crossrod U. It will be seen that by pressing the cross-rod Udownward.with the feet it causes the brake-shoes Q and U to engage therims of the wheels 0, and when the downward pressure on the cross-rod Uceases then the springs U will force the levers U to their formerposition. thereby releasing the brakeshoes Q and Ufrom the rims ofthewheels 0.

The operation is as follows: The le ers I l are raised frotn theirnormal position (shown in Fig. 12) and are moved upward by the operatorin the direction of the arrow b until they assume the position shown inFig. 2. The levers H are then moved downward by the operatorin thedirection of the arrow b", which causes the ratchet-wheel I. andconsequently the shaft A, to rotate. The shaft A receives a similarmotion by means of the lever K, the belt K, and the stirrup K by raising'tltelever Kin theinvcrse direction ol'thearrow to, causing thebelt-pulley J to rotate, which transmits its rotation by means of thepawls J to the ratchet-wheel I, and the latter, being secured to theshaft A, causes the shaft A to revolve, and consequently thedriving-wheel O by the arrangement in the hub B, as before described.The levers H are operated by one person standing on the swingingplatform G, and the levers K are simultaneously raised with the hands ofanother person seated in the seat Gatthesametimethatthe feet ofthisoperator, placed in the stirrups K", press the latter downward, thustransmitting double power to the belt-pulley J. The action of bothoperators on the levers H and K and the stirrups K causes the shaft A torevolve in the same direction, and thus propel the machine forward bythe united power of the two operators.

The swinging platform G affords easy riding on driving the tricycle overuneven or rough ground.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent? 1. In a tricycle, the shaft A, theratchetblock D, provided with the slot D, thesliding pawls D the springsD the hubs 13, and the driving-wheels 0, all arranged as shown anddescribed.
